3 PROPERTIES OF ISOVER PRODUCTS FROM MINERAL WOOL Mineral wool insulation Isover is made from the earths for this purpose. Binders and greasing agents in mineral most abundant materials: rock, sand and minerals of wool products dissolve and evaporate in areas with various types. The production is based on fiberizing temperatures higher than 150 C. As the temperature of molten raw materials consisting of minerals and falls in the direction of the insulations cold side, the different amounts of artificial resins. Mineral wool binder remains unchanged in the greater part of the insulation materials are delivered as wired mats, lamella material. In the outer areas, colder than 150 C, no mats, slabs, blocks, pipe sections and felts. Depending dissolution and evaporation take place. upon the form of delivery, mineral wool insulations can be quilted on wire mesh, faced with foils, glass fleece or glass filament tissue or be equipped with coatings. Isover is part of the Saint-Gobain group, leaders in the design, production and distribution of materials for Final Isover products have the following properties: the construction, industrial and consumer markets. apparent density from 25 to 150 kg/m3 (special fire With a presence in over 50 countries, the groups global protection slabs can have density up to 200 kg/m3), reach allows us to draw on unrivalled financial and very good thermal insulation performance (low technological resources to meet the changing needs of thermal conductivity), customers and communities in the 21st century. In the very good sound attenuation (high absorption Czech Republic Isover has a modern stone wool plant in coefficient), astolovice, Trade Headquarters is in Prague. Thermal, fire resistance non-combustible material, acoustic and fire protection insulations have been high temperature resistance (possibility of application produced in astolovice for more than 40 years. Our up to a maximum surface temperature), company offers a complete range of insulation materials environmental friendly and hygienic, from both stone and glass wool. Thus we can offer you hydrophobisation Isover insulation materials are the optimal product for any industrial application. You made water repellent, will find the best solution with us. long life span (material is not aging), resistant to wood-destroying pests, rodents, and insect, easy to handle, easy to cut with a sharp knife. The Isover product range provides fire safe thermal and acoustic insulation solutions in many applications, including HVAC, original equipment, transport and for tanks and storage vessels. The range of high quality products has been designed to be effective in both performance and cost, while providing ease of installation. Each product is engineered to fulfil specific performance criteria. Maximum surface temperature (MST) is dependent on the apparent density (the higher the density, the higher MST and better thermal performance at high temperature surfaces). Mineral wool insulations have a melting point higher than 1000 C. For outdoor application metal steel jacketing is required. If a product is with an aluminium facing, then the surface temperature must not exceed 100 C on the facing; proper thickness of insulation must be designed 2-3

4 AS quality Melting point of mineral wool Corrosion of stainless steel surfaces under insulation products is an often discussed issue. Highly alloyed austenitic The melting point of mineral wool is determined steel (alloyed by chrome, nickel and molybdenum) are according to DIN 4102 part 17. It is a parameter for predisposed to tensile stress corrosion (stress corrosion the durability of mineral wool insulations in building cracking), which is caused by chloride ions. Austenitic components in case of fire. It must not be confused is a description of crystalline steel structure, therefore with the maximum service temperature and has no identified as AS. Chlorides with water (well-known relation to the service temperature. Mineral wool is classical salt) attack steel surface and cause cracks insulations have the melting point higher than 1000C, in the material. With increasing surface temperature usually in the range from 1200 to 1600 C. the danger of stress corrosion cracking is raised. To minimise this danger, mineral wool insulations in AS Maximum service temperature quality are available for this application. Standard AGI Maximum service temperature according to EN 14 706 Q 132 determines maximum content of chloride ions of (for wired mats, lamella mats and slabs) and EN 14707 10 mg in 1 kg of the insulation material. Mineral wool (for pipe sections) ranging from 250 to 700 C. MST for insulations may be used for insulating objects made various products can be found in a Product data sheet of stainless austenitic steels if the content meets the or at the end of the catalogue in the chapter Isover requirement.

An tester according to EN 12667. The determination of the absorbent layer of mineral wool has the best absorption thermal conductivity of sections is in the pipe tester capacity in the medium and high frequencies (under according to EN ISO 8497.

The higher the density, the higher the thermal performance at high temperature surfaces. In Low thermal expansion our product data sheets declared lambda-values D are Mineral wool insulations have almost zero thermal used; these values are fulfilled within every product. expansion with changing temperatures. A designer will be on the safe side when using our declared lambda-values. That means allowances for Moisture and water repellence workmanship, spacers and supporting constructions are made. Possible inaccuracies caused by calculation All Isover products are treated during manufacture with equations can be eliminated. special additives, which make them water repellent. Isover products are a hydrophobic, non-hygroscopic insulation material. If Isover products get wet, they dry out quickly as a result of the open structure and its mechanical and insulating properties are unaffected after drying. For outdoor application metal steel jacketing is unconditionally required.

5 Basic functions of technical insulations The application of thermal insulation on pipe, vessels and ducts is recognized as a necessary requirement in any construction activity. The thickness and extent of insulation required has always been subject to arbi- trary and imprecise decisions with little engineering or economic input. No material incorporated in a modern construction project provides the owner with as good a financial return throughout the life of the facility as does insulation. The investment in insulation may protect the equip- ment and personnel present during the life of the facil- ity. Proper insulation prevents condensation, chemical corrosion and excessive heat in fire hazard areas. Added human comfort provided by proper insulation in hotels, office buildings, schools or factories adds considerably to the value of the facility and productivity of its per- sonnel. Process temperatures in heat traced piping are more efficiently maintained with proper insulation. The size of the heat generating equipment can be reduced Insulations are defined as those materials which retard when designed with an efficient insulation system. In the flow of heat energy by performing one or more of some cases, insulation is essential to an industrys very the following functions: existence as with the power, the process, and Energy conservation: minimizing unwanted heat loss/ the cold storage. gain from building HVAC systems, as well as preserv- ing natural and financial resources.

6 Heat flow transmission Heat transfer is carried out by three heat transmission Thermal insulations impede conduction, convection and modes: conduction, convection and radiation. radiative effects: by creating a thermal barrier against conduction, Conduction by suppressing air movements, by limiting radiative effects. Heat transfers from warmer surface to colder through solid material or gas (by fibres in mineral wool insulations). The more insulant the material, the less Surface heat transfer coefficient the conduction. Two heat transmissions (convection and radiation) influence the heat transfer coefficient [W/(m2K)]. The Convection higher the heat transfer coefficient, the higher the heat flow rate from a warm surface. Transfer of heat caused by air movements (because of temperature and density gradient). Hot air moves up and heat dissipates. The quieter the air, the less the Thermal transmittance convection. Convection can be natural (when calculating Thermal transmittance (also called Overall heat transfer insulation inside the building) or forced (for calculation coefficient) U (for flat surfaces [W/(m2K)], for pipes [W/ outside where wind blows).

For multi-layer wall: Each material absorbs or emits thermal radiations depending on its temperature and its emissivity. Unlike conduction or convection, heat can be transferred by radiation also in a vacuum. When radiation is absorbed or reflected, there is less thermal transfer.

In boiler rooms, surrounding air temperature is minimally 35 C. Parameters influencing insulation thick- ness design Heat flow from the insulation surface is a function of several parameters which do not relate directly to the quality of the insulation. Here are several parameters that influence design: While there are several choices of insulation materials, thermal conductivity of the insulation material, which meet basic thermal and cost-effective medium temperature, requirements of an installation, choices become more ambient temperature, limited with each additional design objective that external heat transfer coefficient. comes into play. Insulation thickness calculation Economic thickness When calculating the thickness of the insulation it is The most substantial return on an investment in essential to put in appropriate boundary conditions. lt insulation is in energy savings over a period of time. should be noted that the steady-state calculations are Thermal insulation is one of the most, if not the most, dependent on boundary conditions. Often a solution significant technology used to conserve energy, thereby at one set of boundary conditions is not sufficient to reducing pollution. Rising energy costs guarantee an characterize a thermal system which will operate in a increasing return on any investment made in insulation. changing thermal environment (process equipment In fact, it costs less to insulate, than not to. In the case operating year-round, outdoors, for example). In such of steam process and heat, the difference in capital cases, local weather data, based on yearly averages or investment necessary to provide equipment for the yearly extremes of the weather variables, should be extra steam capacity needed on underinsulated systems used for the calculations. and that investment necessary to insulate plus the cost of insulation, still represents a significant capital The heat flow through a surface at any point is a function investment savings. That insulation saves money is not of several variables which are not directly related the issue here. The issue is how much. to insulation quality. Among others, these variables include ambient temperature, movement of the air, roughness and emissivity of the heat flow surface, and 6-7

Because no insulation material This factor is derived from computing a unit installed can completely stop the flow of heat, each increment of price of insulation with the total cost annualized over insulation added to the thickness saves only a percentage the projects life. The unit installed price is a combination of the heat which has escaped through the underlying of the cost of materials, cost of labor and worker insulation. Therefore, each increment of insulation productivity. This is a sensitive variable in the economic saves less than the one before it and must be evaluated thickness calculation. Only the roughest of regional against the cost of installation to determine if it is a averages are available. As a result, care must be taken not good investment. It is possible to determine how much to perceive these estimates as fixed budget prices used insulation applied to a given system will repay its initial for installing insulation. Material prices are related to the costs in a specified time. This point is reached when the volume and cost of the insulation, jacketing, securement, cost of the last incremental of insulation added is offset finishing, and structural support material used. Also by the savings generated by that increment. included in this figure are storage and handling costs to the contractor. Labor costs vary regionally, and include Refer to the stetch on the left. The vertical scale is the wages, fringe benefits, per diem and travel expenses, annual cost. The horizontal scale is insulation thickness. as well as overhead and profit. Labor production varies As the insulation thickness increases from 0, the cost of with pipe size, complexity, number of layers necessary, heat loss through the insulation decreases. Note that this accessibility of piping and surfaces, type of materials cost (line B) tends to approach a horizontal line at high used, and general working conditions. Other costs thicknesses.

C). Line C goes through a minimum value of total annual cost at the Economic thickness. With thicknesses less than the economic thickness, the total annual cost is higher because of the higher value of the cost of lost heat. With thicknesses higher than the economic thickness, the total annual cost is higher because of the higher value of the cost of the insulation. In the case of computer results, each pipe size will be listed with the recommended thickness, as well as the average heat savings (as compared to a pre-listed thickness or bare surface, whichever chosen) and the present value of the heat saved. In order to use any of the available manuals, tables or computer programs, the two cost factors (cost of lost energy and cost of insulation) must be found. The following data is generally provided by the investor. Cost of lost energy This factor is derived from the combination of the rate of energy transfer, the cost of energy and the operational hours per year of the building. Computing the rate of energy transfer requires: surface and ambient temperatures, thermal conductivity of the chosen insulation, the maximum/minimum thickness of insulation to be considered, surface emissivity and last but not least consideration of surface orientation (i .e. vertical, horizontal) and wind (air) velocity.

The program also handles the following calculations: In data sheets of different producers (not only mineral heat loss calculation, wool) you will often find MST and value which is not temperature change in pipes or ducts, measured accordance to EN 14 706. This temperature temperature change in a tank, is only assumed.

Maximum service temperatures for various products can be found at the end of the catalogue in the chapter Isover Products on page 21). Evaporation of binders Binders and greasing agents in mineral wool products dissolve and evaporate in areas with temperatures higher than 150 C. Binder evaporation does not have any influence on thermal properties; only the compactness of a material is decreased.

Isover insulations are due to its fibre structure, an ideal Absorptive structures material for sound attenuation not only for industrial The most common task in room acoustics is to attenuate application. The degree of sound insulation will depend or cancel some frequencies or a whole frequency band. upon the application, the thickness of insulation used This is possible to realise by using convenient absorptive and the nature of any finish used to clad over the material or structures which are frequency-dependent. installation. In suitable frequencies they can absorb up Transmitted energy In this way we can control not only absorption, i.e. Converted energy to 95 % of the sound energy ( = 0.95). reverberation time, but also suppress or completely remove unpleasant sounds. Sound Absorption In a porous material, acoustic absorption is mainly Reflective energy When a sound wave strikes a surface, the sound energy caused by friction in pores, i.e. friction between is broken down into transmitted energy (through the oscillating particles and the surface of pores. Since the converted + transmitted incident material), converted energy (usually heat) and reflected energy (back towards the source of the sound). energy loss due to friction is proportional to the length of the path, the most absorption will occur when the porous material is placed in a position where the particle The more absorbent the material, the less sound is displacement is the largest (maxima displacement). reflected. That part of sound energy which is converted and transmitted is usually expressed as an absorption When sound strikes a rigid wall like concrete, for coefficient . example, a standing wave result and the maxima of particle displacement appear at the distances 1/4, The absorption coefficient for a material varies with 32/4, 53/4, from the surface of a room. These are the the frequency. An absorbent layer of mineral wool critical distances which must be covered by adsorbers, has the best absorption capacity in medium and high i.e. layers with thicknesses d1= 1/4, d2= 32/4, d3= 53/4. frequencies. The absorption in low frequencies is In short, an absorber with a thickeness d placed directly on the solid structure will effectively attenuate only those frequencies, where f c/4d (c is the velocity of sound 340 m/s). For example, insulation thickness of 50mm will reliably attenuate frequencies higher than 1700 Hz, thickness 100mm then already from frequencies 850 Hz. The higher the frequency, the shorter the wave length and better attenuation. An absorbing layer, tightly adjacent to a solid structure, has nevertheless, one disadvantage. To attenuate low frequencies it would be necessary to use very thick layers (for example for attenuation of 500 Hz a thickness of about 20cm would be necessary). Therefore acoustic tiles can hardly attenuate low frequency noise (frequencies lower than 100 dB, such as noise from discotheques). Fortunately, it is possible to avoid expensive acoustic tiles with high thickness. If we use a very thin layer and place it just in the position of the displacement maximum of a chosen frequency, this chosen frequency and its odd multiples will be attenuated. Acoustic tiles thus work as a selective frequency filter. On the selective basis also other acoustic attenuators work, namely membranes, oscillating plates and resonators.

14 General rules for using Isover insulations Between insulated piping sufficient distances must be kept. Valves should be placed without needing to go on the insulated pipes when handling them. Spindle of valves should not be installed in an upward direction to avoid water leakage into the insulation. Surfaces before insulating must be clean and dry. It is not possible to insulate wet or frostbitten surfaces which may later cause damages of insulation or insulated surfaces. Dirt and rust must be rubbed down from untreated carbon steels. Smear and oils must be removed by detergents or solvents from insulated surfaces. Stainless steel surfaces must not be cleaned by detergents or solvents with chloride content. They may be cleaned only by stainless steel brushes. Chloride solution attacks stainless steel surface and causes stress corrosion cracking in the material. With increasing surface temperature the danger of stress corrosion cracking is raised. Piping and equipment from stainless steel can be insulated only by mineral wool insulation in AS quality. Such material can have maximum content of chloride ions of 10 mg in 1 kg of the insulation material. It is necessary to avoid contact of metals which can cause galvanic corrosion (Cu-Zn, Fe-Al). For operating temperatures higher than 600 C aluminium jacketing should not be used. Self-tapping screw, bold or rivet should be from the same material as the jacketing. Surfaces with temperatures higher than 500 C should be insulated by more insulation layers in a way that each layer has a different apparent density. Material with higher density insulates better under higher temperatures than material with lower density; therefore insulation with higher density is placed closer to the hot side. Under low operating temperatures thermal performance is almost equal. Safety working principles must be kept for insulation assembly. Isover products are packed into PE foil. They must be transported in covered vehicles under such conditions to avoid moistening or other degradation. They must be stored in covered places.

Due to its compressive strength resistance they have less demands for undeconstruction (less thermal bridges) in comparison with wired mats. Temporary securing in place is done by aluminium tapes, final fixing shall be done by a baling wire. Insulation pipe section before installation. Protective coverings The efficiency and service of insulation is directly dependent upon its protection from moisture entry and mechanical and chemical damage. Choices of jacketing materials are based upon the mechanical, chemical, thermal and moisture conditions of the installation, as well as cost and appearance requirements. The basic function of the weather protection is to protect the insulation from rain, snow, sleet, wind, solar Protective layer removal from the aluminium self- radiation, atmospheric contamination and mechanical adhesive overlap. damage.

20 Technological appliance to provide compensation for pipe expansion and contraction, insulation to reduce heat flow by staggering joints, thus creating Where big quantities of energy is used, e.g. within a more thermally efficient installation, petrochemical, paper and pulp industries, thermal to achieve thickness in excess of manufacturers insulation is necessary in order to reduce expensive capabilities, energy losses. Tanks, vessels, exhausts, exchangers for retrofitting purposes. and technological piping are appliances that are often working at high temperatures. Good insulation will save Insulation is usually fixed by mechanical fasteners - by energy considerably, which will benefit the environment studs or pins. Spacing between them is dependent on the and keep the working costs down. At the same time design of the vessel, its surface temperature, fire hazard the insulation will reduce temperature fall, which could potential involved and presumptive loading. Each slab disturb the production process. should be fixed by minimally two pins. Boiler insulation Insulations for boilers, kettles and ovens are one of the most demanding applications in industry, because these units are operating at very high temperatures. Good insulation not only saves energy considerably, but the main purpose is personal protection against burn. According to the surface shape and temperature are used either slabs with higher densities Orstech 65 to 110 (for boilers with flat surfaces) or wired mats Orstech DP 65 to DP 100 (for boilers with cylindrical parts). Boiler walls are exposed to very high temperatures (usually around 500 or 600 C). Therefore it is essential Proper insulation can be chosen in accordance with to use mechanical fasteners for the fixing of insulation dimension, surface temperature, the manner of fixing to the surface. Insulation for boilers is done in at least and requirements for jacketing. For pipes and cylindrical two layers; each layer must be staggered when applied. parts are used lamella mats Orstech LSP H and Isover Each layer must be secured in place before the next is ML-3 (only for temperatures up to 250 C) or wired mats applied. A product with high density should be placed as Orstech DP. For appliances and vessels with rectangular the first layer, because it has a higher maximum surface shapes Orstech slabs are suitable (type according to a temperature (higher resistance against high operating surface temperature). Slabs can have aluminium facing. temperatures) and better insulation performace than products with lower densities. If insulation is done in more than one layer, each layer is staggered when applied. Each layer must be secured Chimney insulation in place before the next is applied. The decision to use Insulations for prefabricated chimneys are directly multiple layers may be made for one or more of the supplied by producers of such systems. In cooperation following reasons: with specialized wholesale companies we offer slabs with multi-plate stripes, which allow easy and perfect application for prefabricated chimneys, suitable both for stainless steel chimney liners, as well as with other brands of chimney lining systems. The main advantage is the time saving during the installation in comparison with the use of lamella mats, and horizontal orientation of fibres (better thermal conductivity). Insulation dimensions, i.e. thickness of slabs and groove dimensions dependent on the chimney diameter, are supplied according to customer needs. For non-prefabricated chimneys are mostly used wired mats Orstech DP or slabs Orstech 90 or 110 (for chimneys with rectangular cross-section).
